After receiving a defect petition from a concerned vehicle owner, the National Highway Traffic Safety Administration (NHTSA) is looking into a previously issued extended warranty covering the back glass on certain model year 2005 Chrysler Crossfire Roadster vehicles.
An estimated 15,000 Crossfire vehicles could be impacted.
In a letter dated June 25, 2014, the petitioner expresses concerns regarding Chrysler's decision to limit its extended warranty coverage on the convertible top back glass in 2005 Crossfire vehicles to only certain U.S. states.
In September of 2011, Chrysler extended the warranty coverage on the adhesion of the back glass to those vehicles originally shipped to Chrysler dealers in Alabama, Florida, Georgia, Louisiana, Missouri, North Carolina, South Carolina, Tennessee, and Texas. Impacted vehicle owners in the covered states were provided an extended warranty of 10 years or 100,000 miles on the glass at that time.
The petitioner claims that his vehicle also experienced a separation of the rear glass; however, it is not covered by the extended warranty.
NHTSA's Office of Defects Investigation (ODI) has received 158 vehicle owner complaints that allege rear glass separation on the subject Crossfire Roadster vehicles. There are no allegations of injuries or related crash events.
ODI will now evaluate the defect petition and issue a grant or deny decision. If the petition is granted, further investigation into the matter will commence.
The vehicle owner complaints cited above can be reviewed online at SaferCar.gov.
UPDATE, August 2015:
In assessing the petitioner's request, NHTSA reviewed information from the petitioner, information from Fiat Chrysler Automobiles US, LLC, relevant reports in the NHTSA complaint database received from June 23, 2008 through July 8, 2015, and interviews with complainants.
NHTSA's review indicates that separation of the back glass occurs gradually and the glass remains intact and inside the top after the failure.
The agency says that "considering agency priorities and agency resources, and the likelihood that further investigation would not result in a defect finding, NHTSA has concluded that further investigation of petitioner's concerns is not warranted."
Therefore, the agency has denied the petition. No further investigation into the matter will be conducted. The official petition denial, as published in the Federal Register, can be viewed here.
